Hello guys.
Recently I posted a mail to freebsd-stable list about my problem, but still no response. I'll post my problem here too:

"I have a shutdown problem. I have a machine with gigabyte GA-G33M-DS2R motherboard. Integrated network card is Realtek 8111B. I can not wake the computer after I shutdown it from FreeBSD.
It is a dualboot system - windows xp and freebsd. If I shutdown the computer from windows - later I can wake it up with magic packet. Even if I shutdown the machine on the boot menu with the power button - than later I can wake on lan. The only situation where I CANNOT wake it is when I shutdown the machine from freebsd (halt -p).

First I tested with 7.0-RELEASE-p5 amd64 (RELENG_7_0) and than I upgraded to 7.1 PRERELASE amd64 (RELENG_7). I also tested with two network cards - the integrated one Realtek 8111B and another one Intel PRO1000PT PCI-E with WOL enabled.

With both nics and both freebsd versions the situation is the same - after shutdown from bsd the computer is not able to wake on lan. The indication on the switch port says that after shut down there is active link.

I hope that someone here can help me. This machine should be running 24/7. The reason I need wake on lan is because I have ups in my network, and I use wake on lan to wake up machines in case of shutdown.
